This is the Conservatorium of Music at one of the entrances to the huge botanical garden at the back of the Sydney Opera House. The scene was spotted and shot a minute before the shadow now just showing up engulfed most of the buildings. And the reflection was not obvious at first sight because the photographer was required to really stand on the toes to see it.
So it was by intuition that, when I noticed this pedestal of some sort made from black marble, I went over to see the expected reflection and did the shot. Had I hesitated for a minute, the shadow would have covered the building and blocked out the reflection.
On another occasion, I noticed a really rotten apple core on a flight of dilapidated steps which would make a tasteful image. But I hesitated to stop and missed the shot. More often than not, photographers don't have the time to hesitate.
The next stop is back to Melbourne.
